Quickstart
Shardeum Overview
Shardeum is a blockchain that supports EVM smart contracts.
For more general information on Shardeum:
Cross Shard Composability with Linear Scaling
Shardeum is sharded, allowing the network to scale linearly with more nodes. Horizontally scaling in this fashion allows for high transactions per second at low gas prices.

Wallet Setup For Using Shardeum
You will need an EVM wallet like Metamask to:
-pay for transaction gas fees
-transfer tokens
-interact with smart contracts

To deploy contracts at the same address cross chain:
Deploying Tokens To Shardeum
All EVM based token standards are supported on Shardeum (since Shardeum is EVM compatible). Popular tokens supported on Shardeum:
Cross Shard Composability Communication With EIP-2930
Smart contract addresses that don't have the same prefix are deployed to different shards. The EIP-2930 accessList is used for shard routing contracts on different shards and is automated inside Shardeum nodes.

Integrate File Storage Into Shardeum
We recommend users to use decentralized file storage standards like IPFS and Filecoin.
Files stored on IPFS can be used in contracts to deploy contracts with CID values as shown in this example:
